To ali when?. it 'may concern:

Be it known that I, BENJAMIN M. Das J Aa- DINs, citizen of the United States, and resident of Hartford, in the county of Hartford and State of Connecticut, have invented. certain new and useful Improvements in Tabulating Mechanism for rlfype Writing Machines, of which the following is a specification.

My invention relates to typewriting machines and more especially to tabulator mechanism for such machines.

rfhe tabulating device herein described includes means for quickly setting a typewriter carriage at any point on the scale for the purpose of locating the first letter or figure of a line forming part of a column.

My invention consists in certain features of I construction and combinations and arrangements of parts which will be fully set forth herein and particularly pointed out in the claims.

The present case is a division of my application, Serial No. 723,390, filed July 10th, 1899, for Letters Patent for adding and computing attachment for typewriters.

My invention is illustrated in the accompanying drawings, in which,

Figure 1 is a plan view of the improvements and so much of an' ordinary typewriter as is necessary to illustrate the application thereto of the present invention; Fig. 2 is a right-side elevation of the saine shown partly in section; Fig. 3 is a left-hand View of the typewriter carriage shown in Fig. 1 and the devices supported thereon; Fig. 4 is a front view of the partshown in Fig. 3; Fig. 5 is a front view of the right-hand upper portion of the parts shown in Fig. 1; and 6 is a front View of the keyboard shown in the lower part of Fig. 1.

My tabulator mechanism may be applied to any ordinary typewriting machine. The machine. a portion of which is shown in the drawings, comprises a main frame having a base portion 1, from which risc posts 2, which support a top plate 3. The platen 4 is mounted on a carriage which is so mounted on the machine as to have a motion transversely thereto. The particular means Whereby the carriage is so mounted are immaterirl to my invention and have not been shovvn Serial. N0. 422,963.

herein. Said carriage may be drawn across the machine by any suitable power device such as the spring drum and connections or-` dinarily used in such machines, and the motion of said carriage may be controlled by the usual or any suitable step by step feed mechanism.

The particular tabulato'r mechanism shown in the present case is used in connection with a computer having a casing 5; but my invention is not limited to such use. Said tabulating mechanism comprises a keyboard 6 having a series of keys 7 suitably marked. Each of these keys is mounted on a key lever 8 having a toe 9 which is thrust out when the key is depressed to engage a stop 1-0 on the frame of the computer to limit the downward lmovement of said lever. When the key 7 is depressed its lever is rst rocked to throw the too 9 to position over its stop A1() and then the entire keyboard 6 is carried down, said keyboard being mounted on arms 11 pivotcd on a shaft 12 of the computing mechanism. The stops 10 are stepped as shown in Fig. 6. It Will be perceived that cach key has 1n-independent initial movement during which it does not affect the keyvboard 6 and the parts controlled thereby,

and also a final movement during which it operates said parts, and that the extent of this final movement is different for each key, so that the keyboard is o erated different distances by the different eys. A link 13 connects one of the arms 11 with a sectorgcar 14 which meshes with a pinion 15 on a rock shaft 1G. The shaft 16 has on its u per end a pinion 17 which meshes with a rac 1S and said rack in turn meshes with a pinion 10 on a shaft or stop rod 20 mounted in bearings in the upper part of the typewriter frame adjacent to the carriage. On the shaft 20 are ten radial pins 21 uniformly stepped about the shaft and spaced longitudinally on the shaft at distances apart equal to the units of the typewriter scale. The stepped pins 21 constitute one set of tabulating stops.

Above the shaft 20 and carried in bearings on the usual typewriter carriage (indicated at 22, Fig. 3) is a shaft 23 having a series of pins 24 radially arranged and uniformly spaced about its circumference, the said pins 'the stops 24 to pass the stops 21 being separated longitudinally by amounts which e ual v'ten units of the typewriter scale.- Tie shaft 23 has a beveled gear 25 which meshes with a segment 26. The segment 26 is carried by a rock shaft 27 and on the opposite side o'f the rock shaft is an arm or blade 28 Which is engaged by the stems of a series of keys 29. The plate 2S is tapered and the shaft 27 is inclined to the row of keys 29 as viewed. from above (see Fig. 1) so that the keysv operate on the blade at diflerent distances from the shaft. Each of these keys corresponds to ten units on the typewriter scale and is adapted to render its corresponding stop pin 24 operative. The stop pins 24 may be termed column stops and the stop pins 21 denominational stops. The typewriter carriage is located for the beginning f a number or word at any part of the scale y depressing a key 29 corres onding to the section of ten units in which t e number or word is to be begun and depressing one of the keys 7 to locate the particular unit in the section of ten units. The key 7, through the connections described, rocks the shaft 20 and locates the proper pin 21 in position to engage the pin 24 which is selected by the key 29. While the two keys are depressed the carriage is moved until the two selected pins are in contact. The parts thus adjusted bring the first ligure of a 4number or the rst letter to be written in the desired position. If, for instance, it is desired to begin with the graduation 54 on the typewriter scale, the ey 29 marked 5, and the fourth key from the right of the keyboard 6 would be depressed and the carriage then moved until it was intercepted by the selected pins 21, 24. In the arrangement shown the stops 21 are situated at different distances from the path of the stop or part of the carriage which they are to engage, and each occupies, one after the other, the samenumber-of degree (or angle) around the axis of the' stop carrie so that the required turning of the carrier from any one stop to the next is always of a certain vangle or amount, and the required turning of' said carrier from its normal position to different stops is of different amounts or distances. As shown in Figs. 2 and 5, theseries of stops 21 does not extend entirely around the shaft 20, but said stops are segmentally arran ed about said shaft, an angular space being eft between the end stops of the series. There is also an angular space between each stop and the stop next to it in the series. These inl tervening spaces between the sto s 21 permit eely in the ordinary traverse of the carriage. It will be noted that the sto s 24 are arranged in the` same manner and or the same reason. The shaft 23 and the stops 24 carried thereby conftitute a graduated sto piece which is i; iuted on and is movab e with the carriage, and 1s adapted t0 be adjusted, or

turned to different positions. The series of stops 21 and 24 are each concentrically arranged, being disposed about the axes of their respective shafts 20 and 23 as centers.

It will bejevident that many modifications may be made in -my tabulating mechanism Without departing from my invention.
